DRAM Usage
For features of 8206, Dual 8Mx16 DDR are used.
It is recommended to use dual 8Mx16 DDR (32MB) for following basic features.
Function Full Screen PIP/POP
3D-Comb Y
MDDi Up to 1080i MDDi
When POP mode, Main=AV, Sub=1080I, only one of HD MDDi and Comb
can be enable.
(for POP)Case i: Main=AV(with 3D Comb), Sub=1080i(Bob mode)
(for POP)Case ii: Main=1080i(Bob mode), Sub=AV(with 3D Comb)
(for POP)Case iii: Main=AV(without 3D Comb), Sub=1080i(HD MDDi)
(for POP)Case iv: Main=1080i(HD MDDi), Sub= AV(without 3D Comb)
When PIP mode, there is no constraint in 3D-Comb and MDDi.
Scale mode Normal/Full Normal/Full
VGA timing Up to
1280x1024@75Hz
Up to 1280x1024x60Hz
Panel 1080P
z For PIP/POP mode, 1280x1024 should be under 60Hz.
z Case lists are evaluated when Dram clock = 169 MHz,DDRx2.
Flash Usage
Flash is used to store FW code, fonts, bitmaps, big tables for VGA, Video, Gamma..
In our demo system, we can support 2-4 languages within 1MB flash.
For single country, we need around 20KB to store font data.
For more bitmaps, we need more flash space to store them.
2Mbytes is recommended to build a general TV model.
